i i OF ELGIN,.II. I.INOIS, A CORPORATION OF ILLINOIS i f WATCIICASE f l YApplication mea september 7, 1,927. seen fNQ.' 215,037;

c This inventionrelatesto a watchlcase of three piecesv consisting of case center, a bezel and a back. It relates more particularly to a bracelet type of watch case which is pro- 5 vided with two-pairs of` oppositely extending lugs adapted to support between them strap bars in the usual manner.r .'Thefpresent iinprovements are directed especially to the formation of these lugs, to the manner in which they are carried by the case center,-to the co-v operation between the. lmountiiigs therefor and the case center itself, andto the method by which theseseveral case'parts areprovduced and assembled. l

`An exemplification lof this invention is set forth in the accompanying drawing in the manner following f I. i

Figure 1 isa view in elevation of the watch case in its entirety looking towardthe bezel; Fig. 2 is a side elevation of the case center; Fig. 3 is a View in section taliellon line 3-.3 ofFigQ; Fig, 4 is a view in section taken on line le-Ll O fFigvl; Fig. 5 which is a view similar to Fig. 3 shows a modication in the lug construction; Fig. 6 is` a view in elevation looking toward the-plateforming thebottom of oneV of the case centercon'lponents ;v; y. Fig 7 is asideelevation of the two case center components in assembled relationy Fig. 8 is asimilar view ,of the smaller of these components; f Fig. 9 is an edge elevation of one ofthe bars Fig. 10 is a side-elevation thereof.;V

n The present watch caseis of the three piece type comprising a casey center 1A, abezel B, and a back C. The bezel and back may be Y secured toy the casecenter in any-.approved manner as by a snap connection. f

, The case center "or movement ring herein vshown'is formed of two componentseach substantially a duplicate ofthe other except for size. As shown bestin Fig; 6,,each component p consists of a .plate 11 withupstanding marginal flanges 12..V In the plate is formed a central aperturefle vthrough which the watch movement may pass when being moved into or out of its mounting. The two components of the case center are of such size relatively that'the flanges of one may just it within the ianges of the other. When so related the two plates 11 deline between them adouble walled space wherein a-watch movement may f bereceivedand held:

` The vouter face lof each 'plate may be suitably configured toprovide a meansfor establishing a snap connection with theassociated ybezel Bor back cover C.' This may take the form of a shoulder 17 (see 7 which `is provided on the larger of the two components; When the vsmaller component is fitted within the other, a small edge portion will remain `protruded therefrom to constitute a second shoulder 18.. In this manner,v I Inay provide a means for establishing snap connections with both the bezel and 'back cover, each of whichmay beof'thensual kind.

Formed through the flanges of the two tudinal edges of the case center, and each pro` To connect these two parts of vided with inwardly extending pins22, one

" for each of the holes 19 and 20. The pins whichare entered through ,theseholes `protrude Vslightly beyondv the inner ,face of the inner flange 12, soas to be exposed forswaging. The pins thus constitute rivets Vwhich connect together the two `case parts and also securev theretothe 'two bars 21finthe manner best showninFig. 3. The Vbars may be desirably ornamented or embossed, 'as' suggested in the drawing, so as to enhance the appearance vof the case and having a substanseveral respects.

tial surface in contact with the sides of the case center which serves to appreciably rein torce the finishedarticle. In addition the opposite ends o't' the bars are so formed and extended as to protrude in parallelism beyond the ends ot the case, thus providing lugs 23 in each of which is formed a hole 24. These lugs thus constitute inountings for bars (not shown) to which the ends ot suitable straps or bracelets may be attached.

Certain deviati( may obviously be made troni the construction hereinbefore described without departing essentially from this invention. lne such modication suggested in "F ig. 5 -wherein I have utilized vtour lugs 25, each separately formed, in lieu of two bars the ends ot which provide the desired lugs. In this construction the lugs may be' appropriately tor-ined for mounting uponthe ends of the case, and preferably each is providedwith a tapering foot Qwhich emerges with the contour ofthe case center. The lugs -so formed are vprovided withpins 22 furnishing rivets by which to connect with the case center and join inseparably the two components thereof in the manner already explained. i

The present invention isadvantageous in It may be practicedv by die operations l,which produce alcase 'center ot two parts adapted, when united, to furnish a mounting for awatchmovement. In ad dition it provides for a secure and inseparable connection between the Vparts of the case center so formed, and at the same time provides the lugs which are necessary for the support ot' a bar to :which a. bracelet or strap is attached. In the operations of producing the present case, the two components of the case center are first blanked out and formed up, then interiitted, and lastly connected by swaging of the -jpins which extend. laterally 'from' the lug bars, these latter elements being-themselves se cured to the'case center bythe same means.

'l claim:

1. A watch case in which is comprised a case center formed of two pa.rts'} nesenting double side walls in Iwhich are registering holes, and lug bars substantially engaging the sides of the case and extending from opipositc ends thereof Lhaving means passing through ythe holes of both side walls and engaging with the inner tace thereof ,toprevent withdrawl therefrom, the lug bars Vbeing thereby secured in place and the two walls o't the case center being locked inseparably together.

2. A watch case in lwhich is comprised a case centerhaving double side walls-through which are formed registeringholes,bars extended along and in contact with the outer side walls, `pins extended laterally from 'the barsthrough the proximate ,holes of the .Walls and -upset .against the inner tacesthereof whereby to inseparably lock the walls and bars together.

3. A watch case in which is comprised a case center :termed of two parts each having an apertured plate with an upstanding marginal tiange, the ange on the one part being received within the flange ot the other whereby the two plates are spaced apart a desired distance, there being registering openings through the adjacent marginal walls along oppositesides ot' the case center, and bars 4mounted' in side contact with the outer marginal side walls and carrying laterally extending pins passing through the registering holesthereof, the pins being upset against the inner marginal walls and furnishing an walls of the other with the plates in spaced relation, therel being formed in opposite inarginal side walls registering openings, and pair of bars adapted tobe tittedlagainst the sides of the case center and over the openings through the marginal walls thereof, the ends. ot the bars being extended beyond the ends of the case. and forming'oppositepairs of lugs, and pins extendingflaterally from the bars for passa-ge through the openings in the marginal side walls of the case land adapted to be` secured thereto.
